## Ball Mill Design/Power Calculation

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution The following shows how the size or select the matching mill required to draw this power isMay 02, 2018· An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typicallyWhat is an inching drive? Motion Control TipsThe mill used for this comparison is a 44meter diameter by 136 meter long ball mill with a 5000 HP drive motor It is designed for approximately 90 ston per hourBALL MILL DRIVE MOTOR CHOICES artecmachine
